BESTEK 500W Pure Sine Wave Power Inverter DC 12V to AC(2 Outlets) 110V Car Charger Plug Inverter Adapter Converter with 4.2A Dual USB Charging Ports, ETL ListedClimatePartner certified

Q: how quickly will it inflate a queen sized air mattress?

Its an inverter, not a compressor, so it will inflate your air mattress at the same rate that an overripe banana would... ie, it wont. It cant. So eat the banana and purchase an inflator. Now, if you are using this inverter it to *power* an inflator, then the inflator will work at the same speed as it would plugged into a wall socket. But I’d still eat a banana because its clear you have a potassium deficiency (but I’m not a doctor so you may want a second opinion).

Q: is this a three phase inverter?

500W Three Phase @ $60? In what world is that?

Q: I'll be attaching a relay on the (+) connector, so I'll keep the switch in the ON position all the time, is there a problem with this setup?

Max power draw is very close to 40 amps (34-38 depending on battery voltage). The relay would have to be a 50 amp rating MINUMUM, and higher if you can get it. I believe the next common rating is 70 or 75 amps.

Q: What size are the posts on the inverter? 5/16 or 3/8?

It is neither. The posts on my unit are 3/16, which is adequate for the loop connectors and any load I'll be creating while using the unit.
